This invention appertains to sparkarrestl interfere with the draft ofthe locomotive.

Another salient feature of the invention is the provision of a pluralityof rotatable cylinders arranged one within the other and in the path ofthe products of combustion and having openings therein for permittingthe passage of smoke therethrough and for receiving the cinders orsparks, the screens or cylinders functioning I for retarding the sparksand crushing the same to a powder.

A further object of'the invention is to provide novel means forrotatably mounting the cylinders in the smoke box of thelocomotive andnovel means for mounting the cylinders relative to one anotherwherebythe proper grinding of the cinders and sparks will take place. 7

A further object of the invention'is the provision of novel means forrotating the outer cylinder from a desired moving part of thelocomotive, whereby the cylinders will be positively operated. y v

v A still further object of the invention is to provide a novelcinderand spark arrester and crusher of the above character which willbe durable and efficient in use, one that will'be simple and easy tomanufacture and one which can be placed upon the market and incorporatedwith a conventional locomotive at a comparatively small cost.

With these and other objects in view,'the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed and illustrated in theaccompanying Figure 1 is a fragmentary side elevationof a locomotiveshowing my improved device incorporated therewith,

Referring to the drawings in detail, wherein similar'referencecharacters designate corresponding parts throughout the several views,the letter A generally indicates a 0011- ventionallocomotive andB thenovel spark, arrester and crusher therefor.

As statedthe locomotive is of the usual typeand embodies theconventional boiler 10 having the conventional smoke box 11 thereinforwardly of the flue sheet 12 Communicating with the smoke box' isthe-smoke stack 13. A

Partitions 14; and 15 are: arranged in the smoke box and thesepartitions are spacedso at their forward ends,- as at 16 for receivingthe novel spark arrester and crusher B. ,Arranged directly below thesmoke stack a the partition 14. To one of the drive axles 18 "of thelocomotive'is; secured a sprocket V a wheel 19thepurposeof which willbelater described} a a I r 'The improved spark arrester B comprises innerand outer cylinders .20 and 21. and" an intermediate cylinder 22;\Th'einte'rmediate :cylinder 22 is of a slightly less diameterthan theouter cylinder, while the inner cylinder2Q is of a slightly lessdiamet'er-thanthe intermediate cylinder22. The outer cylinder 21-.is'provlded with end heads"23- and these" heads are connected at theiraxial center to a transversely extendingfshaft 24. The shaft '24 hasits'opposite ends journaledrespectivelyiin the. boiler 10 and in thecover plate i 25, which is provided for the opening '26 in the: smokebox. 5 This lopening=26 provides means whereby the cylinders 20, 21and22'can -be placed inor removed-from the smoke box 11. Any suitabletype of fastening elements 24 and the cylinder rests on 1 the inner sur-1 face of the cylinder 22,while the cylinder 22 rests on the cylinder'2lat the bottom thereof for a purpose hereinafter described,

p a The outer cylinder 21 is provided with circumferential rows ofstaggered slots 28, while the intermediate cylinder2 2 isprovided withlongitudinal rows of staggeredslots29. The

inner cylinder20is provided with rows of slots 30 similar to rows ofslots-28;

v The slots in the several cylinders difier in width. LThosein'the'outercylinder arewider than those" in eitherthe intermediate or the innercylinder and th'ejslots in the interme- 1 diate cylinderareiwider thanthose in the inner cylinder. l

a The outer cylinder2lispositively driven from any preferred par't ofthe locomotive,

"such as-the valve gear'orthelike. In the present instance, "however, Ihave shown the *same'operated from one of the drive axles of 'thelocomotive.iTo carry out this-arrangement the shaft 24 has keyed orotherwise securedtheretora spur gear 31 which meshes with a pinion :32secured to a stub shaft 33.

This stub" shaftis rotatabl-y supported by the "plate 25 and a bracket34: secured to said Eplate. YA sprocketwheel 35 islikewisese cured tothestub shaft and is in alinement & with the ;sprocketl wheel '19 on theaxle 18.

cylinder can be driven in any desired way.

Due to the fact'th'at the cylinder 22 is in engagement with the cylinder21 the same will be rotated thereby and likewise the inner cylinder20'i's rotated due to its contact with the cylinder 22. v

In operation of the improved device, the

products of combustion flow through the cylinders 20, 21 22 and out ofthe smoke stack motive are entirely eliminated. i a 7 Changes in detailsmay be made without departingfrom the spirit or scope of the invention.

I claim:
